Figure 10 is a side elevation, partially in section, along lines lil3 of Figure 9.

Referring to the reference characters in the drawings, numeral I designates a. fruit juice receptacle, which here is shown as being made of glass, and which has associated therewith a removable extractor head or cap 2 carried on shoulder 3, the said top having an extracting cone 4, provided with ribs 5 and ridges 5, and having their beginning at the outer circumference 6 of the cone, and terminating at the apex thereof, whereby to provide for a surface which will cause the maceration of the pulp of the fruit, and the extraction of the juices thereof, upon pressure and rotative contact therewith.

The extractor head 2 has a circular side wall 7 formed thereon, the bottom of which'rests on the shoulder 3, and has provided between the periphery of said side wall and the periphery of said cone a number of openings 8, through which the juice extracted from the fruit during maceration may flow from the head into the receptacle. The receptacle has a handle 9, and a spout l9, through which the juices collected in the receptacle may be discharged without removing either the head or the other elements associated with the same in the extracting device.

The receptacle i, carrying the head 2, is housed in an open ended circular base ll, formed of stamped metal, and having side walls l2, of the same contour as that of the lower portion of the receptacle, it being within the province of this invention to vary the shape and size of such base, so long as it may serve the purpose of removably carrying the receptacle, and the remaining mechanical elements associated therewith, and to be later described.

To the side walls l2 of the base ii, there is fastened, as by means of rivets i3, U-shaped arms l4 and f le which serve as supports for the hollow tubes or pillars l5 and lea, which form part of the supporting assembly for the mechanical elements associated with the receptacle and head carried thereby. The tubes 55 and 6511 are held in vertical position by being fastened to the rightangular base portion 56 formed on the arms M and Ma, and being forced, fit into aperture ill and Na formed in the right-angular projections of the arms 5 4 and Ma, which are directly above and parallel to the base 56. An impaling member ES, comprising of a conical metal stamping, the mechanical details of which will be later described, is carried by a shaft 2! b, supported for rotation on the frame or cross-arm 2i carried on telescoping bars I9 and 2E). The said cross-arm has an opening Zla for receiving such shaft fill), the cross-arm 2! being riveted or soldered to a cap 22, which has an rip-struck rectangular shouldered portion 23, which portion 23 is provided with an opening 23a, associated with opening 2 Ed on cross-arm 2!, to form a two-point support to receive the shaft Zlb.

The handle it is fastened to arm 2%, which arm has a solid boss 25, in which boss the shaft Zlb is fixed, such shaft being passed through the apertures 21a and 23a, so that the boss 25 actually rests on the shoulder portion 23, in this manner providing for the fastening of the impaling member l8 for rotation, and at the same time, for the support of the cross-arm 2! by the telescoping shafts i9 and 2t, reciprocable within the hollow guide tubes i5 and i 5a.

The impaling member E8 is disposed so as to have its surfaces substantially parallel to and at a distance from the projecting surfaces of the cone 3, and has formed therein a series of tangs 25, formed by the stamping out portions thereof inwardly along its body to pierce the skin of the frrit, thereby to cause the same to be restrained in position and to be directed in its movement in accordance with the displacement of the impaling member.

In order to raise the impaling member E8, the arm 26 is raised upwardly, and the cross-arm 25 carried thereby, and the telescoping shafts 3S and 29 are drawn upwardly, so that they may slide out of their respective tubes or guides !5 or its at the same time, so that when the fruit, as shown in the dotted lines of Figure l, is raised above the top of the cone 3 on the head 2, the same may be readily removed from the impaling member it carrying the same.

In order that it will not be necessary to remove the telescoping arms is and 29 from the guide tubes 55 and 55a completely, or to support them while removing the fruit half, pivot joints 26a are provided, as shown in Figures 3 and 4, whereby the larger part of each of the telescoping menu bers l9 and 28, to wit, I90. and 2m may be bent angularly of the shorter arms I92) and 2%, which remain in the tube guides l5 and 55a. Since the pivot joint is of the normal type used in mechanical movements of this nature, no detailed description of the elements forming the same will be given. In this manner, and by the use of such pivot joints, it is possible to raise impaling member to a certain height, (see Figure 4), and then swing the same angularly to left or right, for removing the fruit.

As shown in Figure 5, the telescoping members I90 and 20c are of unequal length, so that when the impaling member I8 is raised to a certain height, the telescop ng arm 200 has still a portion of its length in the tube lfia, while the arm fee is completely out of its guide tube l5,

thereby making it possible to swing the impaling member 58 to the left or right, so as to remove the same and the fruit carried thereby from the range of the cone 3 on the head 2. It is to be noted that once the impaling member in the modification here shown is swung to the left or right, th complete assembly may be carried by arm 2&0, which, when shifted downwardly, rests on the base, and r mains fully within the guide tube i5a.

Modified forms of this invention are shown in Figures 6 to inclusive, in which mechanisms are shown applied in association with shaft 21b, carrying the impaling member, whereby such shaft and the impaling member and the halved fruit carried thereby may be tilted angularly when such impaling member and the cross-arm 2i, carrying the same, are lifted by withdrawal of the telescoping arms i9 and 28, for a short distance, sufficient so that the bottom surface of the halved fruit carried by the impaling member reaches a position above'the apex of the cone 3, without further withdrawing the telescoping arms l9 and 2t.

Referringto Figures 6 to 8 inclusive, there is provided, to co-operate with the cross-arm 2i and the upstruck shoulder 23, a rocker member 28, of rectangular configuration, but having opposing curved bearing surfaces 28a and 282), which rocker member is pivoted within the shoulder 23 by means of screws 29, which pass through apertures in the opposite faces of the shoulder 23, such faces forming a bearing therefor. The shaft -2lb passes through aperture 38 passing through the rocker arm from end to end, so as to provide a connection between the handle 71. and the impaling member l8, means being provided for the angular tilting displacement of the shaft 2Ib through the formation of U-shaped apertures 21 and 21a formed respectively in the upper face of the shoulder and the face of the cross-arm 2| parallel thereto.

When it is desired to tilt the impaling member l8, as shown in the dotted linesof Figure 8, the arm 24 is pushed forward, shaft 25b then caused to clear the U-shaped apertures 21 and 21a, and the curved surfaces 280. and 2832) caused to be disposed adjacent such U-shaped apertures, the screws 29 serving as the pivot of the rocker member in the shoulder.

Referring particularly to Figures 9 and 10, a modified form of rocker arm to provide a tilting action similar to that shown in Figures 6 to 8 inclusive is disclosed, such rocker arm 3| comprising of a cylinder having a central bore 32, through which shaft Zlb passes, and being pivoted by screws 33 passing through apertures in the shoulder 23, there being provided U-shaped slots 34 and 34a in the shoulder and the crossarm faces, in the same relation as described in the disclosure in Figures 6 to 8.

As shown in Figures 8 and 10, the boss 25 has a cutout portion 36b, so as to prevent contact of the surface of such boss with the upper surface of the shoulder 23, when the shaft 2H), carrying the impaling member I3, is tilted, (see the dotted lines showing in Figure 8).

Although the showing herein indicates specific structural formation and configurations of the several elements forming the completed assembly, it is within the province of this invention to vary and alter the sizes, shapes, and relative posi' tions of the elements herein, so long as they may be operably connected to provide for the functions hereinabove described, and hereinafter claimed.
